ABSTRACT

A new pear variety is provided distinguished by its unique coloration wherein 40-60% of the fruit of the new pear variety is colored red with a green background.

GENUS AND SPECIES OF PLANT CLAIMED

Pyrus Communis L.

1. Field of the Invention

The present invention relates to a new pear variety distinguished by its unique coloration wherein 40-60% of the fruit of the new pear variety is colored red with a green background.

2. Background of the Invention

A new distinct pear variety is described herein. This new and distinct variety named ‘Rode Doyenne Van Doorn’ resulted from a spontaneous mutation of the ‘Doyennee du Comice’ variety. The fruit of the new variety is characterized by its late season maturation and a 40-60% red coloring against a green background.

SUMMARY OF THE INVENTION

The new variety is similar to the ‘Doyenee du Comice’ variety. The ‘Rode Doyenne Van Doorn’ variety is distinguished from other pear varieties by its distinct coloration which makes the fruits unique and offers proximate consumers a greater variety of pears from which to choose. Typically, the fruits of the standard ‘Doyennee du Comice’ variety are distinguished by their full green coloration. However, the fruits of the ‘Rode Doyenne Van Doorn’ variety, a mutation of the ‘Doyennee du Comice’, are significantly different in appearance as they have a coloration which is 40-60% red against a green background

Although the appearance of the ‘Rode Doyenne Van Doorn’ variety is different, the new variety maintains many of the same qualities as the ‘Doyenee du Comice’ such as the flavor, texture and perfume. Therefore, the quality of the fruit is not compromised for aesthetic appeal.

Characteristics of the new variety may change to adapt to different environmental conditions such as varying temperature, levels of irrigation, soil conditions and nutrients among other factors. The color descriptions and terminology used herein are used in accordance with their ordinary dictionary definitions unless indicated otherwise.

DETAILED BOTANICAL DESCRIPTION

The following detailed description of the new pear variety, ‘Rode Doyenne Van Doorn’ is based upon observances of the plants and fruits grown and is believed to apply to the plants of the ‘Rode Doyenne Van Doorn’ grown in similar conditions. The new variety is the result of a spontaneous mutation of the ‘Doyenee du Comice’ variety and it belongs to the species Pyrus Communis L.

The new variety was discovered in Province Noord Holland in the Netherlands. Asexual propagation of the new variety maintains uniformity and stability of ‘Rode Doyenne Van Doorn.’ Asexual reproduction of the new variety was performed by the inventor by grafting and budding. The grafting and budding were performed under growing circumstances normal for pear trees with sufficient or regular water irrigation. The new variety is most clearly distinguished from the ‘Doyenee du Comice’ in that 40-60% of the ‘Rode Doyenne Van Doorn’ has a red coloring, whereas typical members of the variety are completely colored green.

The fruits of the new variety are comparable in size to the fruits of the ‘Doyenee du Comice’ variety, which is to say that the majority of fruits produced by the new variety are large. As indicated, the fruit of the new variety is distinctly colored 40-60% deep red on a green background as opposed to the ‘Doyenee du Comice’ variety which is completely green.

Although the amount of growth and size of the fruit in any particular season depends on numerous factors including soil type, rainfall, and root type among other factors, the ‘Rode Doyenne Van Doorn’ shares similar growth habits to the standard ‘Doyenee du Comice’ when subjected to similar conditions. The ‘Rode Doyenne Van Doorn’ variety may be grown in any region in the world suitable for growing fruit trees. Normal temperate conditions are considered suitable for growing the fruits of the new variety.
